By Use Of Non-deforming Work-gripping Clamp And Relatively Movable Clamp, Tool Or Work-forcer Patents (Class 72/293)
  • Patent number: 4052878
    Abstract: This invention relates to a novel tubing bender characterized by a horizontal bed atop which is mounted a template and a fixed block mounting a hollow tubular slide member for non-rotatable longitudinal slidable movement. The tube, in turn, mounts a longitudinally adjustable combination stop and slide support mechanism which selectively engages notches in the template to maintain the tube in longitudinally adjusted position relative to the block. A bending head is mounted on the end of the tubular member for rotatable adjustment relative thereto. The tube is slotted longitudinally both top and bottom to house internally an externally actuated vise mechanism that remains fixed relative to the block atop which it is mounted while the tube and bending head move as a unit longitudinally thereof.
